One solution for the design would be to design the beam as horizontal and split the vertical load on the slope into a vertical and horizontal load on the beam.

If the angle of the slope is theta then model the beam as horizontal and if the vertical load on the slope was P then this is resolved as a vertical load of Pcos(theta) and the horizontal load becomes Psin(theta).

If the angle of the slope is theta then model the beam as horizontal and if the vertical load on the slope was P then this is resolved as a vertical load of Pcos(theta) and the horizontal load becomes Psin(theta).

my ramp has side beams which supports the ramp, i can resolve plate load to be Pcos(theta) that will be my vertical plate load which can be assigned as GY or Locally Z direction, what about my horizontal plate load which is Psin(theta) how will i apply it on the plate?
